![]() To wrap things up, last time I had a similar problem – the machine fed the wire but did not create an arc. Thus, it isīest that you let a professional welder repair technician do the job. Motor SHOULDN’T be fixed at home to avoid worsening the problem. For the ladder, just changing the contact tip will do the trick to get the machine up and running again. And the second one is that the welding tip is blocked by slag or you have burned the wire into it. First, the tension of wire feed system is too loose. A welder that will not feed wire usually has one of the two things causing the issue. If your MIG welder wire feed motor not working, then it is impossible that you can create a continuous arc after your first spark. No need to use pliers, just your fingers and it should be tight enough. For further instructions on how tight the drive should be, I would refer to the owner’s manual.Īre too lazy to see the manual, don’t use too much strength when installing the Little tension, on the other hand, may result in wire slipping. It can cause rough wire feeding as well that can result in arc instability. The gun cable, but if the tension of the drive roll is set too tight, the drive rolls will wear down quicker and Specially made to smoothly feed the electrode wire from the wire spool trough ![]() After that, you can clean the surface with acetone or just with a clean piece of fabric. Messy Weld Surfaceīear in mind that a MIG welder requires clean base metals thus if you are trying to weld on a surface that has oil, zinc, old paint, rust, and other coatings your MIG welder may not start an arc, and even if it does, more than likely you will not get good penetration.įor this reason, we recommend that you clean the surface that you will be welding, using a grinder, sander or at least wire brush to get rid of the coating. This one from Amazon should hold up pretty well. As a piece of advice, get a nice extension cord with thick wires (rated at 30 amps at least for small welder), as it is more sufficient to run a MIG welder. On the other hand, a short extension cord that you usually use in lighting up your Christmas lights is not enough to run a 135-amp MIG welder. With this in mind, if you’re using an extension cord make sure that it is not too long to prevent any voltage drop. If your wire feed is working, then your fuses are okay!Īnother common problem is that you’re running to is small or too long of an extension cord. If your fuses are burned down then the two main causes to that would be a short circuit in somewhere in your workshop or you welded for too long on too high settings and your electricity network just couldn’t handle it. A great idea would be to make sure that you have not blown the fuses. When using a small MIG welder you must have around 110-volts to 120-volts, (you can check it using a multi-meter). However, if you have poor wirings, then this may cause problems. Keep in mind that welder needs the power to work and run. The machine from the power outlet and clean the wires one by one. If that is the case and you have some mechanical skills, unplug Make sure that all the wires inside the machine are intact and are Wires inside the machine get loose or the ground clamp itself needs a Ground clamp may start to malfunction as time passes by. If you try to get a good connection while welding heavy rusty plates then most likely you will not get a spark out of your welder. It might be obvious to some of you, but it is important to note that the ground clamp must be connected on a clean surface. Even experienced welders forget to attach the ground clamp to the workpiece, and if you think that’s the issue in your case, all you need to do is check the ground clamp whether it is connected properly or not. The first and most common problem why usually MIG welder doesn’t make an arc is that the ground clamp is not attached to the base metal properly. To help you, in this article, we will look at some of the common problems why your MIG welder won’t arc as well as some easy solutions to the problems. Knowledge about basic MIG welding troubleshooting methods can help you inįinding the right answer to the issue and continue with your task. One of the common problems that you mayĮncounter in this process is that the MIG welder not arcing. Remember that even when working with the simplest tool you will have some problems. Since it is so easy to control because you only need to operate one element. GMAW is known as one of the easiest and simplest Pieces are joined together using pressure and/or heat.ĭifferent types of welding and one of the most common options is the Gas MetalĪrc Welding (GMAW) or Metal Insert Gas Welding (MIG). Welding is a process in which two or more thermoplastics or metal Fabrication process, welding is one of the most effective methods to bond
